{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.
In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
.Airbags are designed to inflate only once. After
an airbag inflates, you will need some new parts
for the airbag system. If you do not get them, the
airbag system will not be there to help protect you
in another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and diagnostic
module which records information after a crash.
See Vehicle Data Recording and Privacy
on
page 8‑18and Event Data Recorderson
page 8‑18.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
Passenger Sensing System
If the vehicle has the passenger airbag status indicator
pictured in the following illustration, then the vehicle has
a passenger sensing system for the right front
passenger position. The passenger airbag status
indicator, if equipped, is visible on the overhead console
when the vehicle is started.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refers to “ADVANCED
AIRBAGS”.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
.Keep your speed at 55 mph (88 km/h) or less
for the first 500 miles (805 km).
.Do not drive at any one constant speed,
fast or slow, for the first 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake or slow the
vehicle.
.Avoid making hard stops for the first
200 miles (322 km) or so. During this time
the new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
.Do not tow a trailer during break-in.
See Towing a Trailer
on page 5‑42for the
trailer towing capabilities of the vehicle and
more information.
Following break‐in, engine speed and load can be
gradually increased.

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal must
be applied. A (LOCK/OFF) :
This position locks the ignition.
It may also lock the steering wheel and automatic
transmission. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch to
LOCK/OFF.
The steering may bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
Notice: Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
B (ACC/ACCESSORY) : This position lets things like
the radio and the windshield wipers operate while the
engine is off. Use this position if the vehicle must be
pushed or towed.
